Dropper (malware)

A dropper or virus -Dropper is a stand-alone executable file that is used for most first-time release of a computer virus. Computer viruses are not stand-alone executable programs, but only attack other parasitic program code. For this reason, a computer virus for its First Run requires a special support program, the Virusdropper. The dropper itself is a Trojan horse. An on- access scanner an antivirus program can detect heuristically that new machine code to be introduced into an executable file and thus preventing the virus is placed on the system in question.

A further modified form of a dropper, which only stores a malware in temporary storage is called the injector. This version is a little more dangerous because a user the malicious code can not observe directly.

Droppers are often included in files from file sharing networks and camouflage, for example, as a No - CD crack.
